4 BOARD CONFIGURATION AND CONNECTION

The LAN network identifies a physical connection between the microprocessor, the display and the drivers

for the electronic expansion valves. This connection allows exchanging variables from a board to another,

according to a logic established by the software, to make them work together in a functional way. The

address of the boards must be configure even in stand alone unit.

For the configuration of the address of the pCO1 follow these steps:

- connected the pCO1 with a display PGD wich the address configure to 0. (See Address configuration of the

PGD)

- switch ON the power supply pressing simultaneously the ALARM and the UP keys.

- press UP or DOWN key to set the address.

- press ENTER key to save and exit from this procedure.

4.1.2 Address configuration of the PGD

For the configuration of the address of the PGD follow these steps:

- press UP+ENTER+DOWN for few seconds

- press ENTER and then press UP or DOWN key to set the address.

- press ENTER key to save and exit from this procedure.

NOTES:

- If the addresses of the microprocessor or of the PDG are non corrected, the functioning of the unit is not

guaranteed, and the PDG can displays nothing.

- after the address configuration of the PGD, it can display the notice "NO LINK" for some seconds.

4.1.3 Address configuration of the E2V electronic expansion valve's driver

(EVD)

For the configuration of the driver (EVD) is necessary to set

the dip-switch (using a binary logic) that are present inside of

the driver, under the frontal box.:

Driver for circuit 1

Driver for circuit 2

INNOV@-pCO1-IOM-0907-E
